Onde está o ficheiro de configuração do verniz?

queremos encontrar um ficheiro onde possamos escrever esta configuração:

# Maximum number of open files
NFILES=131072

# Locked shared memory, default log size is 82MB + header
MEMLOCK=82000

## Configuration with VCL
#
# Listen on port 80, administration on localhost:6082, and forward to
# one content server selected by the vcl file, based on the request.  Use a
# fixed-size cache file.
#
# Note: you must replace "example.org" with the outside IP address of your server
# - this is the address at which Varnish receives incoming requests.
# $wgSquidServers in MediaWiki's LocalSettings.php will also need to list all addresses for this Varnish cache.
